Sandler told Letterman, "This is a true story…there were very nice people at this place, and let me in with the cheetah and the owner said I could feed the cheetah water with my hands. So I did it, and something went a little bit wrong."

The audience watched in amazement as the video clip was playing. The 46-year-old actor is kneeling before a pool of water with his hands cupped in front of him. Suddenly, the cheetah lunges towards his back. The handler quickly responds and pulls the animal away from Sandler.

The comedian revealed what he did wrong to the late night host.

He said, "What happened was, they said you were not supposed to bend that low with water."

What is surprising about the video is how the funnyman reacted. He kept his cool the entire time. But Sandler shared what was really going on.

"I was very nervous," said the actor. "It was fast… I had a stiff neck at the time, so when he jumped on me, I was like, 'Oh, my neck.'… And when he jumped on me, all I was going to let him do was eat me. I wasn't going to fight back!"
